I've recently moved my Pictures folder into a OneDrive folder on Windows. Within the Pictures folder I had my iCloud Photo folders; this required me to update the location of the various iCloud Photo folders in the iCloud settings. This works fine for the Download and Upload folders, but when I try to update the location for the Photo Sharing folder, it always resets to the previous location.
Note the filepath for iCloud Photo Sharing is
Here's what it looks like after I click the change button and set it to the desired new location:
Note that the iCloud Photo Sharing path is now
If I then click "Done" to exit to the main options panel, "Apply" to apply the changes, and re-enter the Photos Options panel, I see that the change didn't go through (though it noticeably has for the Download and Upload folders):
How can I move the folder and make it stick? It doesn't seem to be a conflict with OneDrive, since even if I direct it to a folder that's not archived by OneDrive, it won't keep the change for the Shared Photos location.
